BACKGROUND

This disclosure relates to a paint stripping system and method of use.

Methods for stripping paint from a metal surface have evolved over theyears. Abrasive blasting is one of the popular methods known in suchindustry. Abrasive blasting method is performed by forcibly propelling astream of abrasive material, such as shot and grit, to smoothen theselected surface. One of the popular devices used for abrasive blastingis a blasting cabinet. This method allows the user to blast a materialwithin the blasting cabinet. Such method can be effective in recyclingthe abrasive material used. Moreover, using such method can contain theabrasive material, dust, and other particulates within the blastingcabinet. Thus, such method can keep the waste contained and can preventcontaminating the environment. However using such method can berestrictive to the size of the blasting cabinet and cannot be used toblast a larger object. Moreover, such method is usually kept at oneplace and is not mobile. Another method used for blasting is pressureblaster, which can be used to blast large objects and/or surfaces. Insuch methods, the abrasive material is released from a nozzle towardsthe selected surface. Thus, this method can be expensive, as it does notsupport recycling of abrasive material used. Additionally it can beinconvenient to use such method when blasting overhead surfaces. As suchit would be useful to have an improved paint stripping system and methodof use.

As such,blaster 101 can be positioned and steered continuously while blastingoverhead surface 1701.

As blaster 101 propels the abrasive material towards overhead surface1701, the waste material and the released abrasive materials can then becollected within second enclosure 302 through upper seal 204. Aspropeller assembly 600 releases the abrasive materials, the abrasivematerials thrown can be collected by left recirculator 500 a, and rightrecirculator 500 b through insert 506. The abrasive materials can thenbe released again from neck 502 of each recirculator 500. This processcan produce a funnel-shaped rotating air within second enclosure 302.The waste material, can be pulled out of the rotating air and can gothrough recirculators 500. The debris can be drawn into first enclosure301 and can go through dust vent 303. From dust vent 303, the debris cango through vacuum hose 206 and into dust collector 103. The debris iscollected and is filtered within dust collector 103. After the debris isfiltered through vacuum pump and filter 1505, the collected waste can bedumped into the waste container of dust collector 103. Once the wastecontainer is full, the waste container can be removed to dispose thedebris.

Simultaneously, the abrasive material produced during operation can berecovered within second enclosure 302 and then goes back to eachrecirculator 500 to be recycled. As the abrasive materials is sent backinto recirculator 500, the abrasive material can curve around firstenclosure 301 and be thrown towards the center. Deflector shield 1001 ofdust vent 303 can slow down the momentum of the abrasive material. Thegravity can then help facilitate with refeeding the abrasive materialinto propeller assembly 600. In some cases wherein some obstacleprevents the abrasive material from being recycled, the abrasivematerial can collect within bottom cavity 504 and within gaps 702. Whenpaint stripping system 100 needs new abrasive material, third loadervalve 1203 c on shot box 1201 can load additional abrasive material tofirst enclosure 301.
